Yields Curves, Recessions and Double Dips

From Caroline Baum of Bloomberg:


Just because nominal long rates can’t go below zero, does that mean the U.S. won’t go into recession?

The yield curve has inverted prior to all of the last seven recessions, with no false signals since 1967, according to Estrella, whose website provides all kinds of research and data for the uninitiated.

Estrella uses the monthly average spread between the 3- month Treasury bill and the 10-year Treasury note to filter out the noise. The lead time between the appearance of a negative monthly spread and recession can be anywhere from three to 18 months. In the most recent instance, the spread turned negative in July 2006, and the U.S. economy slipped into recession in December 2007, according to the National Bureau of Economic Research, the official arbiter of the business cycle.

Under normal circumstances, the current spread of almost 300 basis points between short and long rates would be highly stimulative. Banks can borrow at next to nothing and lend to the U.S. Treasury, pocketing the difference. No fuss, no muss, no credit risk. The profit goes right to the bottom line, helping to recapitalize the banks, which will be in a better position to make loans to creditworthy borrowers.

.....

While a steep yield curve is a sign of an expansionary monetary policy, the Fed needs the banks to get in the game. Instead they’re content to earn the equivalent of the funds rate on the $1 trillion of excess reserves they are holding in their accounts at the Fed.

In this way, the current cycle resembles the aftermath of the 1990 recession when banks, burdened with losses on commercial real estate, weren’t able to expand their balance sheets.

So the best thing the Fed can do if it is concerned about a faltering recovery is keep the funds rate at zero. The short rate is the more powerful tool when it comes to moving the economy. (If it weren’t, why does every central bank in the world target a short rate?) That’s true even though most of us can’t borrow at the interbank lending rate of 0 to 0.25 percent.

“If corporations and banks can fund themselves at zero, credit would not be a problem,” Estrella says. “You could have slowdown for some other reason.”

Slowdown, yes; recession, no. That’s the message of the yield curve. Its track record is impeccable. It beats forecasters, econometric models, even the Fed, which seems to resist the inherent message in the spread.

For all those double-dippers still splashing around in the pool, it’s time to get out, towel off and learn to love a slow recovery.

I've just fallen in love with Caroline Baum. Thanks to this post and a recession discussion with NDd, I've realized, going back to the 1920s, that even the 1929 crisis had a reversed yield curve right before it happened. It took me some time to find the data and to back-test that trading idea with excel but it works out really well.

Anyway, I can't find this relationship on the Japanese market. They've been going nowhere for 20 years and, well, they only did that. I can't find any edge, any interesting pattern nor any reversed yield curve lasting more than a blip. This makes me think that a deflationary environment changes everything and I can't find a reliable tool. But I do have the inverted yield curve in Japan right before the early 1990s crash.

I am quite amazed by this direct relationship. A monetarist friend of mine explained me, point by point, why there was going to be a recession, or a "collapsus" because of the way the yield curve and the monetary aggregates behaved back in 2006-2007 but I didn't understand a word of what he said. I did listen because he was some sort of a ultimate insider but I have only just really understood the relationship between everything that he told me.

"Anyway, I can't find this relationship on the Japanese market."

That is due to the fact that the Japanese equivalent of the U.S. Fed Funds Rate has been below 1% since late 1995. It is nigh impossible to attain an inverted yield curve when the central bank discount rate is hovering above zero.

The Fed Funds rate is currently at 0.19%. Relying upon spotting a yield-curve inversion recession signal with near zero front-end rates is likely to be as reasonable as hunting for ducks in the Paris Metro.

Thanks Francisco :) I do think you are right. However, I've been going through hundreds of japanese data series recently in order to understand what might happen in the US and it seems that :
- the stock market goes right quickly after interest rates are raised while the lag is slower in the US under normal conditions ;
- the unemployment rate produces good results if you short the stock market on peaks when the unem. rate is raising, and inversely.

That would mean that the US economy would have weaker cycles, won't follow the usual real credit cycles and would quickly go into recession at the first negative sign (rate hikes or anything). That's only a possibility but that's what the US turning Japanese would entails.
